Does anyone have any ideas how I can reliably disable a FileSystemWatcher object when my application makes changes to the files in the directory, so that I am only watching for external changes to the directory?
I've tried setting EnableRaisingEvents
to false immediately before performing a write and setting it back to true immediately after, but it seems this method is not reliable, and occasionally I still get the event firing.
The only other thing I can think of is to wait a small amount of time after performing the write to let the OS finish up the modification of the directory before re-enabling the FSW, but that seems hackish and I don't like it.
To add to the problem, the directory consists of potentially many files, the identities of which are beyond my knowledge and control, so I can't just wait for the event to fire for a specific file and then ignore it. There could be any number of FSW events firing after a single modification (because of the potentially many files getting updated).
